Novel thermally stable mesoporous mixed metal Nb-M (M = V, Mo and Sb) oxides were synthesized in the presence of a nonionic Pluronic P123 surfactant. These oxides displayed promising pore structures and chemical compositions for selective oxidative functionalization of propane: high surface areas (up to 200 m2/g), large pore sizes (5-14 nm), and high pore volumes (up to 0.46 cm3/g). The oxidative dehydrogenation of propane to propylene over mesoporous mixed metal Nb-M oxides employed as a probe reaction suggested that the M component was dispersed as the molecular surface species and also formed a solid solution with NbOx in the inorganic walls of these mesoporous mixed metal oxides.
在非离子型普朗尼克P123表面活性剂存在的条件下，合成了新型热稳定介孔混合金属铌- M（M =钒、钼和锑）氧化物。这些氧化物在丙烷的选择性氧化官能化方面展现出了有前景的孔结构和化学组成：高比表面积（高达200平方米/克）、大孔径（5 - 14纳米）以及高孔容（高达0.46立方厘米/克）。以丙烷氧化脱氢制丙烯作为探针反应，研究了介孔混合金属铌- M氧化物，结果表明，M组分以分子表面物种的形式分散，并且在这些介孔混合金属氧化物的无机壁中与氧化铌形成了固溶体。
